Definitions

  • the system generally includes a chassis; a plurality of switch linecards disposed in the chassis and functioning as independent Layer 2 (L2) switches, wherein each of the switch linecards maintains control, forwarding, and interface management functions locally; and a controller, wherein the controller is adapted to configure the plurality of switch linecards as a single network device having a single bridge identifier (bridge ID).
  • L2 Layer 2
  • the blade switch 100 may also be intended to interface with a number of core-facing uplink ports, and the number of uplink ports (i.e., real routed ports 206 ) may most likely be much less than the total number of aggregated ports.
  • the routed ports 206 which function on Layer 3 (L3, the network layer) of the OSI model, may most likely reside on a separate switch linecard 104 than the L2 switches.
  • the routed ports 206 may also be locally managed.
  • the physical external interfaces 106 may be scaled by distributing forwarding information to the switch linecards 104 , as illustrated by the FIBs (e.g., as part of Distributed Cisco Express Forwarding, or dCEF) being distributed to the switch processors 204 and routed ports 206 in FIG. 2 .
  • FIBs e.g., as part of Distributed Cisco Express Forwarding, or dCEF
  • the FIB 314 entry for data packets with a destination address in the subnet of 1.x.x.x should be to rewrite data packets to SVI 2 , through the virtual interface 310 , as illustrated.
  • SVI addressing used in conjunction with the virtual interface routing in the first portion of intelligent forwarding allows data packets to be forwarded as if the linecards (such as BLADE 1 and BLADE 2 ) were connected with point-to-point links.
  • the forwarding engine 318 within BLADE 2 , the second switch linecard 302 , may contain an FIB 320 after configuration of the blade switch 100 that indicates routing incoming data packets to a local interface, such as I 6 and I 7 , to an SVI such as SVI 1 or SVI 2 , or to the virtual interface 310 .
  • a local interface such as I 6 and I 7
  • SVI such as SVI 1 or SVI 2
  • the FIB 320 may contain routing instructions to rewrite the packet to SVI 2 (using local interface I 6 ).
